Background: More than ever before, school principals are dealing with stress and burnout, resulting from increasing role demands and decreasing decision latitude and autonomy. Following the Demand–Support–Constraints model, reasons for stress and burnout can be found in the lack of social support in the environment.

Purpose: This longitudinal study investigates whether changes in social support from colleagues, supervisors and/or the broader community affect levels of principal stress and burnout.

Sample: Approximately 26% of Australia’s school principals took part (N = 3572): primary (n = 2660) and secondary (n = 912) spread across all Australian states and territories. Age ranged between 46 and 55 years, and mean leadership experience was 12 years.

Design and methods: Since stress and burnout are psychological phenomena that develop over time, a longitudinal approach was adopted. Data were collected across four waves, spread over four years, from 2011 to 2014.

Results: It was found that social support predicts decreased stress and in turn burnout in school principals, however differences were found according to the type of social support. The data provide strong evidence for a positive effect of stress on burnout (e.g. the more stress at time 2, the more burnout in principals at time 3) and partial support for indirect negative effects of social support on burnout (e.g. the more support from colleagues at time 2, the less burnout in principals at time 3). However, we also found two instances of positive effects of social support from the broader community on burnout. This suggests that the more support principals receive from the broader community, the more likely they are to show burnout symptoms. This might be explained as the ‘the downside of empathy’, where principals who are strongly supported by their community might also feel more connected to that community. When their community is struggling, they are probably struggling as well.

Conclusions: The findings highlight the positive impact the wider school community can play in providing supplementary professional support to the principal. Unbundling or repackaging the job responsibilities with an administrative team that shares the leadership of the school, could be part of the solution.  相似文献

Floating is the act of staff moving from one unit to another based on the needs of the patients in a hospital. Many staff who float to different units express negative feelings, including anxiety and lack of self‐efficacy. However, floating is an economical and efficient method to use staff across the hospital, especially with current staffing shortages in the United States. This study investigated how the use of mobile performance support devices may help reduce anxiety and increase self‐efficacy for staff who float to different units. With access to multiple resources available on mobile devices, Bandura's social learning theory and self‐efficacy concept set the framework through modeling, observing, and imitating others in order to reproduce certain behaviors and tasks and believe in one's capability to perform. A quantitative study incorporating the retrospective pretest‐posttest design was conducted using the population of float staff, both nurses and respiratory therapists, from Children's Medical Center of Dallas. Both the State‐Trait Anxiety Inventory and General Self‐Efficacy Scale, along with a basic demographic tool, were used to explore anxiety and self‐efficacy in relation to the use of mobile performance support devices. Findings can be used to alleviate the negative feelings of staff toward the idea of floating.  相似文献
